# caddy vs go-micro

caddy and go-micro share 6 technologies: etcd, go.uber.org/zap, Prometheus, OpenTelemetry, go.opentelemetry.io/otel, and github.com/prometheus/client_model. Both are written in Go.

- [caddyserver/caddy](https://seerepo.com/r/caddyserver/caddy): Fast and extensible multi-platform HTTP/1-2-3 web server with automatic HTTPS
- [micro/go-micro](https://seerepo.com/r/micro/go-micro): A framework for agents, tools and services

## What they share and what sets them apart

- In common: etcd, go.uber.org/zap, Prometheus, OpenTelemetry, go.opentelemetry.io/otel, github.com/prometheus/client_model
- Only in caddy: chi, github.com/yuin/goldmark, go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp, go.opentelemetry.io/otel/trace, go.opentelemetry.io/contrib/bridges/prometheus, go.opentelemetry.io/otel/sdk/metric
- Only in go-micro: net/http, go-redis, go-sqlite3, pgx, pq, NATS.io, github.com/nats-io/nats-server/v2, Postgres, RabbitMQ, Redis, github.com/patrickmn/go-cache, MySQL, SQLite, charm.land/glamour/v2, github.com/golang-jwt/jwt/v5, LangChain, Pydantic, go.opentelemetry.io/otel/sdk

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
